From what I hear and see here up in NorCal there is a window during which you will be happy. Waiting for red or brown "hairs" usually happens during the same time that the tricomes are milky. All milky means about THC peak too! If you wait you may have slightly larger more resinous buds, but they certainly will have more CBN and CBD, more body buzz, less brain. We like too take the largest end buds, letting the buds that were covered up more light and nutes, they go from Bs to As in a few days. This can be pretty important in an ouside grow, when you take the outermost and heaviest buds you have shortened and strengthtened each branch and that can make a big difference when that rains come right before you finish harvest. Thanks for you great work.
